SLIDE BUCKLE.`

Application leid October 31, 1927. Serial No. 230,020.

shoes known as pumps. These buckles com` prise a frame having a strap-engaging slide which is mounted on a cross-bar of the frame and is slidable longitudinally in the frame to engage and release one of the two straps, the other strap bein fixed to the frame. It 1s desirable to tuck tie first-mentioned strap beneath the far end of the frame so as to conne its free end, but the thickness or bulk of the overlying straps requires a considerable space between the fixed strap and the frame that is not obtainablein the ordinary buckle frame which is `stamped and drawn from metal. My invention is designed to afford this space, and it consists in drawing down a divided cross-bar in two parts, and connecting these parts by a separate sleeve, so that a. cross-bar may be obtained of sufficient dept-h to receive the straps without impairing its strength and stability, as I will proceed 'now to explain and finally claim.

In the accompanying drawings illustrating the invention, in the several ligures of which like parts are similarly designated, Figure l is a top plan view;` Fig. 2 is a bottom plan view; Fig. 3 is a longitudinal section, and l? ig. 4 is a transverse section on line 4-4, Fig. `3, of a. slide-buckle embodying the fea tures of my invention in one form.

The frame may be stamped or drawn from suitable inet-al, and consists of the sides 1, ends 2 and 3, and intermediate cross-bar 4, the last being depressed from the plane of the sides,

`as shown in Fig. 3. On the cross-bar 4 is mounted a clamping slide 5, having its end `6 looped about the cross-bar so that said slide may have a longitudinal sliding motion on said cross-bar. The leading end of the slide extends toward and beneath the end 3 of the frame, and in advance of said end has a transverse slot 7, the rear edge 8 of which is elevated so as to bend the strap and add to the security of the engagement of the two, as indicated b the dotted line part 9,V representing the a instable strap.

Ordinarily a cross-bar is located between the end 2 and the cross-bar 4, by depressing the metal of the frame, but in order to obtain a sufficient depth to receive the anchoring strap 10 and the overlying, tucked-in strap 9,

the necessary drawing down of the metal in the form of a continuous cross-bar would so attenuate the metal as to make it too weak to stand the strain of use. Instead of this, it is common to form a separate bar of the desired depth of depression and attach it to the frame by riveting or solde-ring or other means; but this is a. laborious and costly pro cedure. The enumerated and other objectionable features of prior buckles, I overcome by depressing the cross-bar in two separate parts 1l and 12, with inturned ends 13 and 14 alined and secured by a sleeve l5 extending from one of the parts to the other and inclosing said ends 13 and 14. The metal in the usual processing will stand for only a limited depression. Ordinary steel and brass can be drawn into a relatively long and narrow strip to Within about one-eighth inch limitation; but present trade requirements necessitate a bar that is depressed about one-fourth inch belowA the level of the face of the buckle, and such depression is met by dividing the bar as above stated. Thus there is afforded a rigid and stout cross-bar, of sufficient depth to afford space for bot-l1 straps, and of greater depth than is ossible by drawing the entire cross bar, an without impairing its strength and with little, if any, increase in labor and costs.

The dotted-in illustration of the straps 9 and l() in F ig. 3, is believed to show the use of the buckle and the clamping or gripping of the strap 9 by the slide. 5, without further explanation.

By my invention a satisfactory slide buckle is provided which will meet fully the condi tions imposed by the use of thick straps.

Variations in details of construction are permissible within the principle of the invention and the scope of the claims following.

The use of the buckle of this invention is not confined to the straps of pumps, but may integral bar, and a transverse sleeve connect- Y ing said separate parts.
